Disabling a button? by ryxdp on 04-12-2009 at 06:53 AM

Well, I've looked around in the docs and it seems there is no property to enable/disable a button in a PlusWnd, but I thought it must be possible using SendControlMessage() or even Interop.Call(). I tried the former, using the message 0xA (WM_ENABLE) but it's apparently only for windows. So is there a way to disable and enable buttons in the interfaces?

Thanks :)

Javascript code:
var ControlHandle = PlusWnd.GetControlHandle("TestBttn");
Interop.Call("User32", "EnableWindow", ControlHandle, 0 /* Change to 1 to enable */);

Thanks :P I had no idea those kinds of functions worked on controls as well.

Actually, what we call a control is nothing more than a child window in a parent window with some very special capabilities. :) This means you can also send window messages to a control and (if Plus! would support this) monitor control notifications.
